- FIG. 1 is a block diagram of the components of an automobile 2 .
- Automobile 2 includes an engine 4 , a catalytic converter 6 , a heat exchange unit 8 , an engine control unit (“ECU”) 10 , a generator 12 , a main battery 14 , an auxiliary battery 16 , an air conditioning unit 18 , and an electronic accessory 20 .

- automobile 2 is a hybrid vehicle.
- automobile 2 can be any type of vehicle such as a vehicle with an internal combustion engine, a vehicle with a hydrogen engine, a vehicle with an ethanol engine, etc.
- the present invention is not limited to just automobiles, but may also encompass any type of transportation units such as airplanes, helicopters, tanks, trucks, etc.
- Engine 4 is connected to starter 34 , generator 12 , catalytic converter 6 , and ECU 10 .
- Engine 4 is utilized to move automobile 2 but can also be used to power main battery 14 through generator 12 .
- Engine 4 can be activated by starter 34 and is monitored by ECU 10 . Once activated engine 4 generates heat during the combustion process and waste air is generated. The waste air from the combustion process is passed to catalytic converter 6 and can have, for example, a temperature of about 1600 degrees Fahrenheit.
- Engine 4 transfers the waste air to catalytic converter 6 .
- Engine 4 can be an internal combustion engine, a hybrid engine, a hydrogen engine, a natural gas engine, an ethanol engine, or any other type of engine sufficient to generate power to move automobile 2 .
- Starter 34 is connected to engine 4 and auxiliary battery 16 . Starter 34 receives energy from auxiliary battery 16 and is used to activate engine 4 .
- Generator 12 is connected to engine 4 and main battery 14 . Generator 12 can generate energy for main battery 14 using power supplied by engine 4 .
- Main battery 14 is connected to generator 12 and heat exchange unit 8 .

- Main battery 14 can also be used to power a motor (not shown) which could aid in driving or moving automobile 2 .
- main battery 14 is a high voltage battery.
- Catalytic converter 6 is connected to engine 4 , ECU 10 , and heat exchange unit 8 .
- Catalytic converter 6 receives the waste air from engine 4 and cleans the waste air to reduce the toxicity of the waste air. This can be accomplished, for example, through chemical reactions. Catalytic converter 6 then transfers the waste air to heat exchange unit 8 .
- Auxiliary battery 16 is connected to starter 34 , air conditioning unit 18 , heat exchange unit 8 , and ECU 10 . Instead of being charged solely through engine 4 via an alternator, auxiliary battery 16 may be charged through heat exchange unit 8 . Thus, in one embodiment, the alternator can be removed from automobile 2 as the alternator would be unnecessary. Advantageously this can reduce a load on engine 4 and a weight of automobile 2 . Both of these factors can allow automobile 2 to be more efficient. Auxiliary battery 16 can supply power to electronic accessory 20 and/or air conditioning unit 18 .
- Air conditioning unit 18 is connected to heat exchange unit 8 , auxiliary battery 16 , and ECU 10 . Instead of receiving its energy from engine 4 , air conditioning unit 18 can receive energy directly from heat exchange unit 8 or indirectly from heat exchange unit 8 through auxiliary battery 16 . By receiving energy from heat exchange unit 8 instead of engine 4 , a generator and/or solenoid may be removed from automobile 2 . That is, instead of connecting a generator and/or solenoid from engine 4 to air conditioning unit 18 , air conditioning unit 18 can be connected to heat exchange unit 8 and/or auxiliary battery 16 . Advantageously this can reduce a weight of automobile 2 . Furthermore, if engine 4 can operate without having to drive a generator and/or solenoid, this can also reduce a load or strain on engine 4 . By reducing a weight of automobile 4 and the load or strain on engine 4 , this can improve the fuel efficiency of automobile 2 as well as reduce the production cost of automobile 2 .
- Electronic accessory 20 is connected to heat exchange unit 8 , auxiliary battery 16 , and ECU 10 .
- Electronic accessory 20 can be powered directly through heat exchange unit 8 or indirectly from heat exchange unit 8 through auxiliary battery 16 .
- Electronic accessory 20 can be, for example, an audio device, a video device, an audio/video device, a fan, a mobile phone, or any other types of electronic equipment that can be used in an automobile.
- ECU 10 is connected to engine 4 , catalytic converter 6 , heat exchange unit 8 , generator 12 , main battery 14 , auxiliary battery 16 , air conditioning unit 18 , and electronic accessory 20 .
- ECU 10 can monitor and/or control the functions of engine 4 , catalytic converter 6 , heat exchange unit 8 , generator 12 , main battery 14 , auxiliary battery 16 , air conditioning unit 18 , and/or electronic accessory 20 .
- Heat exchange unit 8 is connected to catalytic convertor 6 , auxiliary battery 16 , air conditioning unit 18 , electronic accessory 20 , and ECU 10 .
- Heat exchange unit 8 receives the waste air from catalytic converter 6 . Although the waste air may have lost some of its energy during the catalytic conversion process in catalytic converter 6 , it still possesses sufficient energy to produce a state change in a material from a liquid to a vapor.
- Heat exchange unit 8 can be constructed from material that provides high temperature resistance such as stainless steel or other alloys. It may be advantageous to have heat exchange unit 8 be located as close in location to catalytic converter 6 in order to reduce the loss of energy by waste air through transportation of the waste air from catalytic converter 6 to heat exchange unit 8 .
- FIG. 2 is a block diagram of a heat exchange unit according to an embodiment of the present invention.
- Heat exchange unit 8 includes a core unit 22 and energy generation modules 24 , 26 , 28 and 30 .
- core unit 22 receives the waste air from catalytic converter 6 and uses the waste air to generate vapor by transforming a liquid to vapor using the heat from the waste air. This can be accomplished, for example, using an accumulator and valve systems (not shown).
- the liquid is isolated from the waste air such that heat can be transferred from the waste air to the liquid, but the liquid and the waste air do not actually mix. This can be done, for example, by using thermo conductive material to segregate the waste air and the liquid.
- the vapor generated by core unit 22 is then selectively passed to energy generation modules 24 , 26 , 28 and 30 .
- Energy generation modules 24 , 26 , 28 and 30 can each be designed for a specific range of vapor pressures and the appropriate energy generation module or energy generation modules are activated depending on the vapor pressure in core unit 22 . That is, energy generation module 24 might be optimized for used with a relatively high vapor pressure whereas energy generation module 30 may be optimized for use with a relatively low vapor pressure.
- an energy generation module that is configured to be connected to a device that utilizes a high energy output is configured to be used with relatively high vapor pressures because it is contemplated that relatively high vapor pressures can generate a higher amount of energy. For example, since energy generation module 28 is connected to air conditioning unit 18 , energy generation module 28 is configured to be used with a relatively high vapor pressure.
- each energy generation module 28 can be accomplished by configuring the turbines within each energy generation module. For example, to generate a higher amount of energy with higher vapor pressure, it is contemplated that relatively large turbines are used. Furthermore, smaller turbines can be used where there is a relatively smaller vapor pressure available since smaller turbines can be more easily activated with less pressure than larger turbines.
- each device connected to heat exchange unit 8 is connected to a separate energy generation module.
- Each energy generation module is controlled by ECU 10 and can be activated or deactivated depending on the vapor pressure of the vapor supplied by core unit 22 .
- energy generation modules 24 , 26 , 28 and 30 are modular such that they can be easily removed and replaced with other energy generation modules without having to remove and/or replace heat exchange unit 8 .
- this allows damaged energy generation modules to be replaced without having to replace the entire heat exchange unit 8 which can reduce the maintenance cost of heat exchange unit 8 and further extend the life of heat exchange unit 8 .
- energy generation modules 24 , 26 , 28 and 30 are modular, then if new devices are added to automobile 2 , new energy generation modules can be added to appropriately address the power consumption needs of the new devices.
- more efficient energy generation modules may be developed, in which case the more efficient energy generation modules may replace the original energy generation modules.
- a user activates engine 4 .
- engine 4 is generating waste air that has waste heat at a high temperature.
- the waste air is transported to catalytic converter 6 where a chemical conversion process is undertaken at the high temperature to reduce the toxicity of the waste air.
- the waste air is then transferred from catalytic converter 6 to core unit 22 of heat exchange unit 8 . Since the waste air still has an extremely high temperature, core unit 22 utilizes the waste air and the extremely high temperature of the waste air to vaporize a liquid within core unit 22 .
- the vapor produced by core unit 22 is then sent to an appropriate energy generation module.
- the appropriate energy generation module is then selected by ECU 10 . This can be done by examining the vapor pressure of the vapor in core unit 22 , the devices which require energy, and the energy generation module which the devices which require energy are connected to. For example, if the vapor pressure had a gauge pressure of 100 psi, and electronic accessory 20 , air conditioning unit 18 , and main battery 14 are active, then in one embodiment, ECU 10 selects one or more energy generation modules from energy generation module 30 , 28 and 24 .
- ECU 10 can select energy generation module 28 to be active since it is optimally configured to handle 100 psi to 200 psi and the vapor pressure is 100 psi.
- ECU 10 can also activate energy generation module 24 and 30 instead of energy generation module 28 since energy generation module 24 is optimal for vapor pressure ranges 40 psi to 50 psi, and energy generation module 30 is optimal for vapor pressure ranges between 60 psi to 80 psi.
- the sum of the vapor pressure ranges would be 100 psi to 130 psi, and the vapor pressure is 100 psi which would be within the range of optimal vapor pressures.
- the corresponding devices can receive power from auxiliary battery 16 . If auxiliary battery 16 is low on charge, a warning can be issued to the user of automobile 2 to reduce the amount of devices the user is operating or the energy usage of the devices such as by reducing the air conditioning power. Furthermore, ECU 10 can also optionally deactivate some devices in order to recharge auxiliary battery 16 .
- the present invention utilizes relatively hot waste air, which was previously discarded, allowing engine 4 of automobile 2 to function more efficiently by reducing the load on engine 4 and also reducing the weight of automobile 2 . It is contemplated that with the present invention, the fuel efficiency of automobile 2 can be increased by approximately 15% to 20%. That is, if a conventional automobile was getting 45 miles per gallon (“mpg”) prior to implementation of the present invention, automobile 2 with implementation of the present invention may get 54 mpg after implementation of the present invention.
- mpg miles per gallon
- FIG. 3 is a block diagram of a heat exchange unit according to an embodiment of the present invention.
- Heat exchange unit 8 in FIG. 3 has a single energy generation module 32 instead of multiple energy generation modules as seen in FIG. 2 .
- Core unit 22 transfers the vapor to energy generation module 32 and energy generation module 32 generates energy such as electricity from the vapor. This can be accomplished, for example, through the use of one or more turbines.
- devices such as main battery 14 , auxiliary battery 16 , air conditioning unit 18 , and electronic accessory 20 are connected to energy generation module 32 instead of separate energy generation modules.
- a switch (not shown) controlled by ECU 10 can be used in energy generation module 32 to determine which of the devices energy generation module 32 should send energy to.
- core unit 22 still produces vapor but sends the vapor to a single energy generation module 32 .
- Energy generation module 32 then utilizes the vapor to produce energy such as by using turbines.
- ECU 10 then controls which devices (e.g., main battery 14 , auxiliary battery 16 , air conditioning unit 18 , and electronic accessory 20 ) should be connected to energy generation module 32 to receive power from energy generation module 32 .
- the present invention can have insulative or heat retention materials on the engine to allow the engine to retain heat to generate waste air with even higher temperatures. This could allow more energy production from heat exchange unit 8 and also reduce the load on engine 4 .
- heat exchange unit 8 is combined with catalytic converter 6 .
- heat exchange unit 8 can replace the existing catalytic core and refracting liner.
- Heat exchange unit 8 can include tubes and fins designed to provide maximal thermal transfer with a minimal backpressure.
- ECU 10 can activate an energy generation module even when the vapor pressure is outside the optimal vapor pressure for the energy generation module. For example, if the vapor pressure is 80 psi, and the optimal vapor pressure for the energy generation module is 40 psi to 60 psi, the energy generation module may still be activated. Likewise if the vapor pressure is 30 psi, and the optimal vapor pressure for the energy generation module is 40 psi to 60 psi, the energy generation module may still be activated.
- a second heat exchange unit (not shown) is connected to heat exchange unit 8 and receives the waste air from heat exchange unit 8 . This could allow for more efficient energy capture from the waste air.
- the second heat exchange unit (not shown) is connected to catalytic converter 6 in parallel with heat exchange unit 8 .
